Models the Q dependence of the QENS line width (Gamma (hwhm)), diffusion coefficients (D), residence times (tau) and jump lengths (l) to extract the associated long range diffusive motions of molecules.
The Hall-Ross Jump diffusion model [1] has the form:
Units of are inverse units of
.
Units of are
if units of
are ps.
Alternatively, units of
are
if units of
are ns.
Name | Default | Description |
---|---|---|
Tau | 1.0 | Residence time |
L | 0.2 | Jump length |
